Suka Jātaka (No.255)

The Bodhisatta was once a parrot. When he grew old his eyes became weak and he was looked after by his son. The son once discovered a special kind of mango on an island, and, having eaten of it himself, brought some home to his parents. The Bodhisatta recognised the mango and warned his son that parrots visiting that island were short-lived. However, the son took no heed, and one day, while flying back from the island, he fell asleep from weariness and was eaten by a fish.

The story was told in reference to a monk who died of over-eating. The parrot is identified with him. J.ii.291‑4.
